简介一边听听音乐，一边写写文章。
| 一、文件签名验证 #include <Softpub.h> #include <wincrypt.h> #include <wintrust.h> // Link with the Wintrust.lib file. #pragma comment (lib, "wintrust") BOOL VerifyEmbeddedSignature(LPCWSTR pwszSourceFile) { LONG lStatus; DWORD dwLastError; // Initialize the WINTRUST_FILE_INFO structure.

This implies that the identity of the publisher has been verified by a certification authority. 2) In cases where user interface is displayed (which this example does not do), WinVerifyTrust will check for whether the end entity certificate is stored in the trusted publisher store, implying that the user trusts content from this publisher. 3) The end entity certificate has sufficient permission to sign code, as indicated by the presence of a code signing EKU or no EKU. */ GUID WVTPolicyGUID = WINTRUST_ACTION_GENERIC_VERIFY_V2; WINTRUST_DATA WinTrustData; // Initialize the WinVerifyTrust input data structure. // Default all fields to 0. memset(&WinTrustData, 0, sizeof(WinTrustData)); WinTrustData.cbStruct = sizeof(WinTrustData); // Use default code signing EKU.
